NSE4 Question #211: Real Exam Question with Answer & Explanation

Question

Because changing the operational mode to Transparent resets device (or vdom) to all defaults, which precautions should an Administrator take prior to performing this? (Select all that apply.)

Options

• ABackup the configuration.
• BDisconnect redundant cables to ensure the topology will not contain layer 2 loops.
• CSet the unit to factory defaults.
• DUpdate IPS and AV files.

Explanation

Changing a FortiGate's operational mode to Transparent resets the device to factory defaults, necessitating a configuration backup and a review of network topology to prevent Layer 2 loops.

Common mistakes.

• C. Setting the unit to factory defaults is precisely what happens automatically when changing to Transparent mode, so explicitly performing this action beforehand is redundant.
• D. Updating IPS and AV files is a regular maintenance task for security hygiene but is not a direct precaution for the configuration reset or Layer 2 implications specifically caused by changing the operational mode to Transparent.
